My parents drama

My mom and dad are recently separated. I had to move her in with me because he was verbally and physically abusive towards her. He's been cheating on her for years and she only recently found out. I'm mad at her too because she cheated on him a few months back. I guess she was frustrated and tired but this happened while I was telling her about my husband cheating and she was gunning me advice not to leave him etc. my dad probably thinks now that I hate him. I'm angry at them both but I don't hate them. I guess the relationship with my dad might be going down hill because of all this drama and today is fathers day.........I feel sorry for them both. He doesn't even get along well with my bro so I was really the only one who spoke to him with no hard feelings. Sigh
